I wanted a new tower defence game: So I made one
The examples given for real world things The Golden Gate Bridge and The Hoover Dam, are instances of things. Things that the class of which they belong is old enough that Dam and Bridge are not new words.
If you are making new things you need a new name. Software is inherently new because computers have been in wide use for only a few decades. Instances of software rarely even get names, just numbers, with project names or nicknames attached. I'd be willing to bet both The Golden Gate Bridge and the Hoover dam had project names or nicknames.
